BPEL in a Service-Oriented Architecture

A good example of BPEL here....

In order to illustrate what problems BPEL addresses and how it relates to SOA, we'll consider an example from the travel industry. Consider a company offering travel services over the Web. The operations might include:

getAvailableHotels: Takes an input of an airport code and returns a list of hotels near that airport.
getDescription: Takes an input of a hotel identifier and returns a description.
getRate: Takes as input a hotel identifier and the type and number of rooms and the date and provides a quote for the rate.
makeReservations: Takes an input of the hotel identifier and the dates.
cancelReservation: Takes a confirmation number and cancels the reservation.
